The list of implied organizations is a list of organizations that have not physically appeared up in any form of media to this point in time. Regardless of their lack of appearance, implied organizations have been mentioned at least once throughout the Mario franchise.

Boyz II Pumpkins is a contemporary band mentioned by Frogfucius in the Super Mario RPG: Legend of the Seven Stars Nintendo Player's Guide.[1] Frogfucius cites the band as an example of the poor music being produced in the contemporary era, compared to the music he grew up with as a child. He states: "When I was a wee tadpole, we had real music. None of this Boyz II Pumpkins nonsense." The name Boyz II Pumpkins is a combination of two real world recording groups, both popular in the 1990s: Boyz II Men, an R&B group, and The Smashing Pumpkins, an alternative rock group. Indeed, Frogfucius, as a stereotypical "elderly person," may simply be confusing each group as the same band, producing the name "Boyz II Pumpkins."

Mario and Luigi hoped Mr. Lasagna would recruit them for the team. Unimpressed with both their skills and their cooking, Mr. Lasagna decided to bring their meatballs back for his team to practice with in lieu of actual baseballs, and offered them jobs tossing peanuts at ballgames.

The Brooklyn Plumbing School is a school at which at which Mario and Luigi were members of the band for three years. The band is called the Brooklyn Plumbing School Band. The only mention of these organizations was by Mario and Luigi during The Super Mario Bros. Super Show! animated episode "The Pied Koopa". During the episode, Toad asks the brothers if they can play the instruments they had created out of Bowser's Castle's plumbing. Luigi responded that they had been in the band. Mario commented that they were thrown out for eating during a concert. Luigi maintains that he was not, but had simply held Mario's salami sandwich while his brother turned the page. Because of this, it can be inferred know they sat in close proximity. Mario had made a trumpet while Luigi created a trombone, two instruments that are classically situated nearby one another.

Mr. Gibbel is known to be a high-ranking member. Members such as Mr. Gibbel wear a brown costume with a chipmunk emblem on the front with a matching chipmunk hat, and greet other Chipmunks in a chipmunk-like manner. The Chippie Chipmunks have a contest every month to see which member is worthy of becoming Chipmunk of the Month through performing enough good deeds. The winner is evaluated on a points system, and receive a Secret Chippie Decoder Ring at a special awards ceremony roughly one week after winning.

Goldbobbington's is a large corporation that Goldbob the Bob-omb owns. It was mentioned during Paper Mario: The Thousand-Year Door. Not much is known about this corporation, only that it is a wealthy organization. If Mario speaks to Goldbob's wife Sylvia at some point during Chapter 3, she erroneously refers to the corporation as "Golbobbington's" (spelt without the D).

The only mentioning of the Grand Order of Plumbers was in The Super Mario Bros. Super Show! live-action segment "Plumbers of the Year", in which the Grand Order of Plumbers sent the Imperial Poobah to grant Mario and Luigi the status of Plumbers of the Year.

Hafta Havit Hairdryer Hotline Corp, or HHHHC, is a mail-order company, presumably headquartered on Earth, mentioned in Mario is Missing!. Little is known about them apart from the fact that they sell hairdryers. Bowser ordered many hairdryers from them in his campaign to melt the Earth's polar ice caps. As a result, their stock went through the roof, and they were rather angry that Luigi put a stop to the Koopa King's scheme.

The Kingdom News Network (KNN) is presumably a news station that broadcasts in the Mushroom Kingdom. The Lakitu Bros. work as eyewitness reporters for this network, as revealed in the Super Mario 64 Nintendo Players' Guide. The game itself also mentions that they work for a news station, though it goes unnamed in game.

The Luigi Fan Club is, as the name suggests, a fan club for Mario's brother, Luigi mentioned in Paper Mario: The Thousand-Year Door. There are only two known members of this fan club, Toadia (from Poshley Heights), the secretary, and an unnamed Toad from Petalburg, the leader. These two characters provide the only mentions of the club. Several other characters in the game also state their favoritism of Luigi, especially in Petalburg.

The secretary ironically mistook Mario for Luigi because Mario was wearing a green hat and shirt. When she met the real Luigi, she called him a fake.

Little is known of the Pidgit Express, though its possible it is a mercenary group, as King Koopa, through a phone call, hires a dozen Pidgits to attack Mario, Luigi, Toad and the genie's flying carpet through it. However, only nine Pidgits come, though it is still said that it is a pack of twelve. The name may have been a play on the defunct low-cost airline People Express.

The Public Broadcasting Service (PBS) is a Real World nonprofit organization that specializes in the distribution and broadcasting of public television programs. The network's program lineup includes educational shows related to history, science, and the fine arts; dramas and documentaries; music shows; public affairs programming; and children's shows.

In the context of the Super Mario World episode "Rock TV," the network is only known to play nature related television shows. Mario and Luigi prepared to watch their Koopasonic Rock TV for the first time, and Princess Toadstool declared that she and Yoshi would not watch it, but would go on a nature walk instead. Mario considered the possibility that the pair might appear on PBS.

Sigil Securities is a global company in Wario: Master of Disguise. Carpaccio, who mention Sigil Securities several times, is the head of it. It is known that Carpaccio used the financial might of this company to develop a morphing technology that helped him become Head Honcho Carpaccio.

Carpaccio says that the slogan of the company is, "We're hard at work watching your back... that way it's easier to pick your pocket."

The Nintendo News is the name of the company who makes newspapers which Wario reads the begging of Wario Land 4. Only one issue is seen with the discovery of the Golden Pyramid on the front cover. Note that the name "The Nintendo News" is not actually visible during normal gameplay, but it is part of the newspaper sprite.

Kolorado, the Koopa archaeologist from Paper Mario, was also one of Professor Frankly's students. As such, it is likely (although not confirmed) that Kolorado attended U Goom. This would also imply that the university was not strictly a school for Goombas.
